:Germanium
Beschreibung:
Germanium ist ein chemisches Element mit dem Symbol Ge und der Ordnungszahl 32. Es ist ein Halbmetall, das sowohl Eigenschaften von Metallen als auch von Nichtmetallen aufweist. Germanium ist typischerweise ein glänzender, grauweißer Feststoff, der spröde ist und eine diamantähnliche Kristallstruktur hat. Es wird hauptsächlich in der Halbleitertechnologie verwendet, insbesondere in Transistoren und Dioden, aufgrund seiner Fähigkeit, unter bestimmten Bedingungen Elektrizität zu leiten. Germanium hat einen relativ hohen Schmelzpunkt und ist bei Raumtemperatur in der Luft stabil, obwohl es sich beim Erhitzen oxidieren kann. Es ist auch bekannt für seine optischen Eigenschaften, was es nützlich in der Infrarotoptik und der Glasfaseroptik macht. Germanium kommt in der Natur nicht in seiner elementaren Form vor, sondern wird aus Erzen wie Germanit und Argyrodit gewonnen. Obwohl es als wenig giftig gilt, sollte der Kontakt mit Germanium-Verbindungen sorgfältig gehandhabt werden, da einige schädlich sein können. Insgesamt spielt Germanium eine entscheidende Rolle in der modernen Elektronik und Materialwissenschaft.
